Castillo San Felipe del Morro (El Morro)

Commissioned by King Charles I in the 1539, El Morro is one of the most iconic landmarks in Puerto Rico. This massive fort was designed to guard the entrance to San Juan Bay and protect the city from seaborne enemies. Today, it stands as a testament to Spanish military engineering and offers breathtaking views of the Atlantic Ocean.

  • Highlights: Explore the dungeons, barracks, and cannon-firing positions. Don't miss the lighthouse and the expansive green field in front of the fort, perfect for picnicking and kite flying.
  • Fun Fact: El Morro is a UNESCO World Heritage Site, recognized for its historical significance and preservation.

Castillo San Cristóbal

While El Morro defended San Juan from sea attacks, Castillo San Cristóbal was built to protect against land invasions. Covering 27 acres, it is the largest fortification built by the Spanish in the New World.

  • Highlights: Walk through its tunnels, visit the sentry boxes (or garitas), and enjoy panoramic views of Old San Juan. The Garita del Diablo (Devil's Sentry Box) is steeped in local legend.
  • Fun Fact: San Cristóbal is connected to El Morro by a series of walls that encircle Old San Juan, creating one of the most significant military architecture complexes in the Americas.

La Fortaleza

La Fortaleza, also known as the Palacio de Santa Catalina, is the official residence of the Governor of Puerto Rico. Constructed in the early 16th century, it is the oldest executive mansion in continuous use in the Western Hemisphere.

  • Highlights: The building itself is a stunning example of Spanish colonial architecture. While it's an operational government building, guided tours are available that cover its history and significant events.
  • Fun Fact: La Fortaleza has been listed as a UNESCO World Heritage Site since 1983.

Catedral de San Juan Bautista

This cathedral is one of the oldest buildings in San Juan and the second oldest cathedral in the Americas. Originally built in 1521 and reconstructed several times, it houses the tomb of the Spanish explorer and first governor of Puerto Rico, Juan Ponce de León. While this Baroque style cathedral was first built in 1521, wasn't officially completed until 1802.

  • Highlights: The gothic architecture, the tomb of Ponce de León, and the beautiful stained glass windows.
  • Fun Fact: The cathedral is still in use today and hosts regular services, making it a living piece of history.

Paseo de la Princesa

One of, if not the most scenic walkway in Puerto Rico. This promenade, dating back to 1853, is perfect for a leisurely stroll. It runs along the southern city walls of Old San Juan and offers stunning views of the bay. The Paseo de la Princesa is a great starting point for sightseeing in Old San Juan.

  • Highlights: Statues, fountains, and street vendors line the walk, leading to the Raíces Fountain, a popular photo spot. The pathway is particularly beautiful at sunset.
  • Fun Fact: This is the only remaining city gate of the Walls of Old San Juan.

Casa Blanca

Built in 1521, Casa Blanca originally served as a fortification for San Juan Islet as well as a house for Juan Ponce de León and his family. Casa Blanca is one of the oldest structures in San Juan. Although Ponce de León died before he could move in, his family lived there for over 250 years. The building also served as the first Governor's residence in Puerto Rico.

  • Highlights: The house has been converted into a museum, showcasing 16th and 17th-century artifacts and offering insights into the early colonial life.
  • Fun Fact: Originally constructed out of wood, after a fire destroyed the build it was rebuilt with stone and masonry.
